WATER-HEATER,

Specification of Letters Patent.

Patented Nov. 2, 1915.

Application filed October 30, 1914. Serial No. 869,381.

To all whom it may concern Be it knownthat '1, SMITH C. WELLS, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Water-Heater, of which the' following is a full, clear, and exact description.

The object of the invention is to provide' a new and improved water heater, more especially designed as an attachment to a steam generator, such as is used in apartment houses, hotels and like bu1ldings for furnishing steam to radiators in the various rooms for heating purposes, and arranged to dispense with separate water heaters for supplying the tenants with hot water.

In order to accomplish the desired result, use is made of a casing mounted in the combustion chamber of-thesteam generator and provided with a circuitous passage for the water, the said passage being connected at one end with an inlet pipe and at the other end with an outlet pipe, the said pipes being connected with a hot water supply tank.

A practical embodiment of thG lHVGIItIOH is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the water heater as applied to a steam generator of the sectional type, part of the generator being shown broken out; Fig. 2 is a side elevation of the same with the part of the steam generator in section and part broken out; Fig. 3 is a sectional plan view of the casing of the water heater; Fig. 4 is a front elevation of a portion of the casing of the water heater and one of the suspending rods for supporting one end of the casing in the combustion chamber, a part of the heater casing being shown in section; Fig. 5 is a front elevation of a modified form of the suspension for the casing of the water heater as applied; Fig. 6 is a sectional plan view of the same on the line 66 of Fig. 3; Fig. 7 is a front elevation of the water heater as applied to a horizontal tubular steam generator, part of the steam generator being shown in section and part broken out; and Fig. 8 is a side elevation of the same with part of thesteam generator in section and part broken out.

As shown in Figs. 1 and 2, the-"casing-A of the water heater is located in the upper portion of the fire box or combustion chamber B, directly below the lowermost row of water-circulating tubes 0 of a steam generator of the sectional or similar type. The casing A is preferably of rectangular shape and cast in one piece (see Fig. 3) and the interior of the casing is provided with a circuitous passage formed by partitions A A extending alternately from opposite ends A A of the casing A. The partitions A terminate a short distance from the end A while the partitions A terminate a short distance from the other end A whereby the water is caused to flow slowly through the circuitous passage, to insure a quick heating of the same from the heat in the fire box. or combustion chamber B. The entrance end of the circuitous passage in the casing A is connected with a supply pipe D connected with a hot water supply tank E connected by a pipe F with the discharge end of the circuitous passage in the casing A.

The pipes D and F extend over some of the water-circulating tubes C, as plainly indicated in Fig. 2, to support the rear end of the casing A by the said pipes D and F.

The front end of the casing A is supported by suspension rods G tapped into the top of the casing A and extending upwardly between the adjacent tubes C, each rod terminating at its upper end in an eye G through which passes a bar H resting on top of the said adjacent tube C. By the arrangement described the casing A is conveniently held suspended in the upper portion of the fire box or combustion chamber B, so that the heat emanating from the burning fuel in thefire box heats the casing A and the water circulating through the same.

The supply pipe D is provided with a check valve I and a controlling valve J for controlling the water passing through the pipe D from the tank E to'the casing A. The return pipe F is provided with a controlling valve K and with a blow-ofi' pipe L located outside of the steam generator at a point between the valve K and the casing A.

. The blow-ofl pipe L is provided with a valve L so that the water passing through the casing A. carries the sediment along and discharges it through the pipe L to a pail or other suitable receptacle held at the end of the pipe L. In practice, the pipes D and F pass through the openings normally covered by the cleaning-out doors O arranged on .the front of the steam generator, and the said doors are provided with recesses O for the pipes to pass to the outside of the steam generator and then to the tank E, as previousl explained.

T e suspension illustrated in Figs. 5.and 6 is in the form of rods G each extending at its lower end through a slot N formed in a corresponding plug N screwing in the front end A of the casing A, the same as above described in reference to the plugs N. The lower end of each rod G is threaded and engaged by nuts G G abutting against the top and bottom of the-plug N to securely hold the rod G in position on the said plug. The upper end of the rod G is provided with an eye G for the reception of a bar H,

the same as above described and shown in Fig. 2. y

In the modified form shown in Figs. 7 and 8, the casing A is turned around so that its ends are embedded in the side walls P of the steam generator, and in this case'the pipes D and F extend through the side walls of the steam generator to connect with the receiving tank E. Otherwise the construction of the water heater is the same as above described in reference to Figs. 1,

2 and 3.

1 By reference to Fig. 8, it will be noticed 4 that the casing A forms a deflector for the having an interior circuitous passage for the water, means for heating the same comprismg a combustion chamber in whlch the said water heater is arranged, an inlet plpe con- 7 nected with one end of said passage, an outlet pipe leading from the other end of the saidpassage, means for supporting the pipes, the said pipes extending into the combustion chamber and forming a support for one end of the said water heater, suspension means connected with the said water heater at theother end thereof, controlling valves in the said pipes, and a valved blow-off pipe connected with the said outlet pipe at a point intermediate the valve of the outlet pipe and the water heater.

25A water heater, comprising a casing made in one piece and having an interior circuitous passage for the water, means for heating the same, including a combustion chamber, an inlet pipeconnected with one end of said assage, an outlet pipe leading from the ot er end of the said passage. means for supporting the said pipes within. the combustion chamber, the said pipes forming a support for one end of the water heater, hanger arms attached to the said water heater' at the other end thereof, spaced supports within the combustion chamber, and between which the said hanger rods extend, and supporting rods resting on said supports and engaging the said hanger arms.

3. In a water heater, a casing having a circuitous passage therein, inlet and outlet pipes attached to one end of the casing at the ends of said passage and forming a support for said end, horizontally arranged supporting rods engaging fixed supports,

and vertically arranged hanger arms having eyes at their upper ends engaged by said supporting rods, the said hanger arms being secured at their lower ends to the other end of said casing.

4:. In a water heater, a casing provided with partitions extending alternately from.

opposite ends, and forming a circuitous passage, means for heating the casing including a combustion chamber, inlet and outlet pipes attached to one end of the casing at the ends of said passage, supports for said pipes within the combustion chamber, the said pipes forming a support for one end of the casing, screw plugs screwing in the other end of the casing opposite the free ends of the partitions, said screw plugs being provided with slots, suspension means for the last mentioned end of the casing and including hanger arms extending at their lower ends through the said slots in the plugs, and means for holding the hanger arms in position.

In testimony whereof I have signed my name to this specification in the presence of a subscribing witness.
